Measured Against Yesterday

A scaler learns its smallest and largest values from the training readings. New readings are then measured against those numbers, even when they fall outside them.

Task: write scale_new(train_values, new_values).

• Fit a MinMaxScaler on train_values only (one column).
• Use it to transform new_values, without learning anything from them.
• Return the scaled new values as a list, each rounded to 3 decimal places. Values below 0 or above 1 are fine.
